SPECIFICATION forming part of Letters Eatent No. 757.489, dated April 19, 1904. Application filed August 27, 1903- Saris-11in. 171.024. (No model.).

To It whom it may concern.-

Be it known that I, JAMES HARRY Nrcnon SC-N, of New York, in the county of New York and State of New York, have invented certain new and usefui Improvements in VVail-Furring; and I do hereby declare the following to be a fuil, clear, and exact description of the invention, such as Will-enable others skilled in the art to which it appertains to make and use the same. The primary object of this invention is to provide improved studding for fireprhof building construction.

A further object is to provide improved means compiernentary to the studding for holding the fireproof slabs in position. I

The invention will be hereinafter fully set forth, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a perspective view. Fig. 2 is a sectional View of the studding. Figs. 3 and i are edge and plan views, respectively, of the preferred form of clip. Fig. 5 is a slight modification thereof. Fig. 6 shows the end stud. Fig. 7 shows slabs in position. Referring to the drawings, 1 designates a building-wall of brick or other construction.

2 designates the studding employed at either end of a section of furring. It is shown as consisting of strips, preferably of wood, square or rectangular in cross-section and provided with metallic sheathing. These strips are designed to be secured to the building-wall in a vertical position to support the slabs 3 at their side edges,.th us providing the necessary airspace between the wall and furring.

4 designates the studding designed to accommodate adjacent slabs. This consists of a metallic member or a series thereof corresponding in height to that of the vertical series of slabs and provided with angular portions 5, having flanges 6, the latter designed to be secured to the building-wall. The studding is preferably made from a single piece of metal bent at its sides to form the angular portions and flanges. The bridge of the studding 4 is designed to form a'seat for the slabs 3,

its angular portions 5 corresponding in length air-space between the slabs and building-wall.

The studding is provided with a series of lon gitudinal slots 7 designed to register with the space intermediate adjacent slabs.

8.designates the clips or securing members by which the siabs are secured to the studding 4E. \Vhen in position, these clips are of approximately 1 shape and are designed to have their central body portions 9 movably held within slots 7, so that their inner lateral flanges 1O willengage the inner face of the studding, while the outer flanges 12 overlap the slabs and retain the latter in place. (See Fig.- 7.) As shown in Figs. 3 and 4, the clips may be made [from a metal plate cut to form a tongue constituting the central body portion 9 and the latter divided longitudinally at its free end to form ears or flanges designed to be bent in opposite directions to constitute the inner securing members 10. In the modification shown in Fig. 5 the plate is divided longitudinally at both of its ends, and the adjacent flanges thus formed are bent in opposite directions. 1n the use of either form the clip .is positioned in the studding in the manufacture of the latter and the inner flanges bent to their normal positions.

In constructing the furring the studs carrying the clips are first secured to the buildingwall. The side edges of the end slabs of asection are secured to studs 2 and the othei'edges placed in contact with studs 4, after which the clips are moved through their slots and slipped over the slabs to hold the. latter, the frictional engagement of the clips insuring their remain- 1 ing in their adjusted positions, although the end walls of the slots would prevent the clips entirely slipping from the slabs.

The advantages 'of my invention are apparout to those skilled in the art to which it re-' lates. It will be noted that the stud a, being in one piece, insures the slabs being held in the same plane and relative positions. This advantage is obviously not attainable where separate studding members are employed to support adjacent slabs. It willv furtherbe noted that the clips and studding are readily assembled in'the manufacture and that the for- 1 mar are easiiy new we in a wail cnnstruetien, the comhizstion with slabs arranged in pemiiei series of studding'designed t0 euppari; the slabs--02 adjacent series, such sigudding censisfiing of an appro: ma'teiy iii-shape member having; its bridgen poriion forming for the slabs and pmvided with P. series of 5106s., clips movable in such slots and normaliy engaging the studding attheir inner ends and their outer ends engaging and holding the slabs rhe stmiding.
